7 Detailed Description

7.1 Overview

The TPS51117 is a synchronous buck controller for POL voltage regulation in notebook PC applications. The

controller is dedicated for the operation of the Adaptive On-Time D-CAP mode. This mode provides ease-of-use,

low external component count, and fast transient response. Auto-skip mode for high efficiency down to the

milliampere load range, or PWM-only mode for low-noise operation is selectable.
